Two seed diaries, several possible explanations

Compare documented conditions before suggesting reasons for different outcomes.

If the light, water and starting materials all differ, a difference in germination does not isolate one cause. Read the setup notes alongside the observations before suggesting why the records diverged.

Read both diaries' methods before comparing outcomes. Similar-looking seeds may have experienced several different conditions during the observation period.

Different watering and light conditions make a single-cause explanation uncertain.
